“…However, NMDA receptor antagonists were found to attenuate mechanical, but not thermal, hyperalgesia to a moderate extent , although a number of studies did not demonstrate this effect e.g. . A similar reduction in mechanical hyperalgesia, but not on thermal hyperalgesia, was observed when ketamine was combined with the opioid receptor antagonist naloxone , indicating that coadministration of naloxone does not reduce the effects of ketamine.…”

“…The pain threshold was measured every minute on the fourth finger of the right hand by applying pressure using an algometer (Somedic, Sollentuna, Sweden). 11 Pupil size was measured continuously with a video camera. We encouraged the subjects to verbalize their subjective experience before and during the test and asked if they felt any discomfort.…”

“…In volunteers submitted to burns, racemic ketamine decreases central sensitization both by intravenous 82,83 and subcutaneous 84 routes. This effect has not been observed with oral administration 85 . Intravenous ketamine decreases acute pain intensity caused by experimental electric stimulation 86,87 .…”

“…Em voluntários submetidos a queimaduras, a cetamina racê-mica reduz a sensibilização central tanto pela via venosa 82,83 como pela via subcutânea 84 . Esse efeito não foi observado por via oral 85 . A cetamina venosa diminui a intensidade da dor aguda causada por estimulação elétrica experimental 86,87 .…”
